What is Metso's Latest Acquisition in Recycling Technology?

Metso has signed an agreement to acquire TL Solution's recycling operations and induction heating technology development capabilities. This Finnish company, based in Oulu, has been a key collaborator with Metso on recycling technology development for several years. According to Global Mining Review, the acquisition is expected to be finalized in August 2025, with the transaction value remaining undisclosed and having no material impact on Metso's financial outlook.

The acquisition represents a strategic move that brings proprietary induction heating technology fully under Metso's control. This technology has been instrumental in Metso's sustainability transformation initiatives, particularly in mill lining recycling services.

"Metso started mill lining recycling development more than 10 years ago," explains Martin Karlsson, SVP of Mill Lining at Metso. "By acquiring TL Solution's recycling operations, we gain complete control over technology development and implementation."

The Strategic Importance of the Acquisition

The acquisition significantly strengthens Metso's in-house recycling capabilities in several ways:

• Technology ownership: Brings proprietary induction heating technology fully under Metso's control
• Development continuity: Builds upon more than a decade of mill lining recycling R&D
• Quality assurance: Enables consistent, high-quality recycling services through complete process ownership
• Vertical integration: Reduces dependency on external technology providers

This strategic acquisition aligns with Metso's long-term commitment to developing circular economy solutions for the mining industry, reinforcing their position as an innovator in sustainable mining technologies.

How Does Metso's Mill Lining Recycling Technology Work?

Metso pioneered the market with its innovative Poly-Met™ mill liner recycling services using induction heating technology, which was launched in 2022. This first-of-its-kind service represents a significant advancement in sustainable mining practices, addressing the end-of-life challenges of composite mill linings.

The technology centers around specialized induction heating systems that enable the separation of different materials in used mill linings without damaging potentially recoverable components. This selective heating process targets specific materials within the composite structure, allowing for efficient separation.

Technical Innovations in the Recycling Process

The recycling technology acquired from TL Solution incorporates several innovative approaches:

• Targeted induction heating: Selectively heats metallic components at specific frequencies
• Material-specific separation: Enables efficient separation of rubber and metal components
• Preservation techniques: Maintains integrity of recoverable materials during processing
• Dedicated processing line: Purpose-built facilities for handling used mill linings

The technology specifically targets Metso's Poly-Met™ mill liners, which combine metal and rubber components in a composite structure. These linings are particularly challenging to recycle through conventional means due to their mixed-material composition.

Karlsson highlights that "the acquired technology significantly strengthens our recycling capabilities based on induction heating, allowing for efficient separation of materials for reuse and recycling."

Why is Mill Lining Recycling Important for Sustainable Mining?

The mining industry faces increasing pressure to reduce waste and improve sustainability across operations. Mill linings, which protect grinding mills from wear, represent a significant opportunity for material recovery and reuse due to their substantial metal content and relatively predictable wear patterns.

Traditional disposal of worn mill linings typically involves sending them to landfills or industrial waste facilities, contributing to mining's environmental footprint. Metso's recycling approach transforms this linear consumption model into a circular one.

Environmental Benefits of Mill Lining Recycling

Mill lining recycling delivers multiple environmental advantages:

• Landfill diversion: Significantly reduces industrial waste volumes from mining operations
• Resource conservation: Decreases demand for virgin materials in new mill lining production
• Carbon footprint reduction: Lowers emissions associated with new material extraction and processing
• Circular economy advancement: Establishes practical closed-loop systems for mining consumables

These benefits align with the mining industry evolution and its growing focus on improving environmental performance and meeting increasingly stringent sustainability requirements from investors, regulators, and customers.

Economic Advantages for Mining Companies

Beyond environmental benefits, mill lining recycling offers tangible economic advantages:

• Disposal cost avoidance: Reduces expenses associated with industrial waste management
• Potential value recovery: Creates opportunity for credits or value from recovered materials
• Compliance preparedness: Positions operations ahead of potential future recycling regulations
• Sustainability reporting: Provides quantifiable metrics for corporate sustainability goals

As Martin Karlsson notes, this approach "supports circular economy principles in mining by extending material lifecycle and reducing waste," creating a win-win for both environmental and economic considerations.

How Will This Acquisition Enhance Metso's Service Offerings?

What Does This Mean for the Future of Sustainable Mining Equipment?

This acquisition signals a growing trend toward sustainability and circularity in mining equipment manufacturing and services. As the mining industry faces increasing pressure to reduce environmental impacts, equipment manufacturers are responding with innovative solutions that address the entire lifecycle of their products.

Metso's move reinforces the emerging industry standard that equipment providers should take responsibility not just for selling and maintaining equipment, but also for its end-of-life management and material recovery.

Industry Implications

The acquisition has several important implications for the mining equipment sector:

• New performance standards: Establishes recycling capabilities as an expected service from equipment providers
• Supply chain transformation: Shifts focus from linear to circular material flows in mining equipment
• Investment redirection: Encourages R&D spending on recycling technologies across the industry
